The soft rubber products commonly seen in daily life, such as phone protective covers, waterproof gloves, waterproof rings, toothbrush grip handles, and various wheels, are all made of soft rubber. However, product design and development personnel may choose different raw materials based on their respective factories and customer needs, with rubber, silicone, and TPE materials being the most common.

There are many varieties of rubber, mainly including natural rubber and synthetic rubber according to their sources; According to its scope of use, it can be divided into two categories: general rubber and special rubber. Various types of rubber have different properties and characteristics due to different manufacturing methods, molecular chain structures, compositions, etc., and are therefore suitable for different rubber products.

Silicone material is actually a type of synthetic rubber under rubber, which is a thermosetting elastomer with the advantages of safety and non-toxicity. It is insoluble in water and any solvent, non-toxic and odorless, and has stable chemical properties. It does not react with any substance except strong alkalis and hydrofluoric acid, and has high adsorption performance, good thermal stability, and chemical stability.

TPE is a thermoplastic elastomer that combines plastic and rubber properties. It exhibits high elasticity of rubber at room temperature and can be plasticized at high temperatures. It is a polymer material that can be widely used in the automotive industry, daily necessities, household goods, tool kit adhesive, sports equipment industry, watch straps, and more. TPE material is not only easy to produce and relatively cheap, but also can be recycled, which can reduce a lot of costs. It is an environmentally friendly product.

Reasonable material selection needs to be considered based on the comprehensive performance of the material in the product's usage environment. The main properties that soft rubber products pay attention to include hardness, elasticity, corrosion resistance, weather resistance, susceptibility to cracking, coloring performance, high (low) temperature resistance, cost, processing technology, etc.
